- Free 411 (800-373-3411) If you don't mind listening to a 10-second ad first, Free 411 lives up to its name, giving you free business and residential listings (which can optionally be delivered via text message). Thanks to reader kwright for the tip on this one!
- GOOG-411 (800-466-4411) Google's 411 service is surprisingly ad-free, though it limits you to business listings. Like Free 411, it can automatically connect your call and/or send you the listing via SMS. See it in action in the above video.
- Live Search 411 (800-225-5411) Microsoft's 411 service offers not only business listings, but also traffic and weather reports, movie showtimes, travel resources, and more. (Live Search also powers Microsoft's Tellme service.)
